PAPER-MACHINE FRAME.

SPECIFICATION forming part of Letters Patent No. 389,576, dated September 18, 1888.

Application filed February 18, 1888. Serial No. 264,467. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV KAFFENBER-GER, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Paper-Machine Frames, of which the following is a specification.

This invention pertains to the frame parts of paper-machines, and will be readily understood from the following description, taken in connection with the accompanying drawings, illustrating my invention in connection with the drier portion of a paper-machine- Figure 1 being a side elevation of a drierframe carrying seven base-pieces and three superdriers; Fig. 2, a vertical transverse section of one of the housings H; Fig. 3, a per spective view of one of the roll-boxes; Fig. 4, a perspective View of a bushing for one of these boxes; Fig. 5, a vertical'transverse section of one of these boxes with the bushing shown in end elevation; Fig. 6, a face view of one of the arms B, carrying the boxes of the spring-roll U; and Fig. 7, a side view of the same with the joint portion shown in section in a plane parallel to the pivot of the joint.

In the drawings, A represents one of the longitudinal walls for the support of the framing; B, a sole-bar resting thereon and provided with a continuous bolt-slot in its top, it being understood that there is of course a wall and sole-bar along under each line ofseatframing of the machine; 0, a chair engaging downwardly upon the foot of the sole-bar, the intention being that there shall be one of these chairs at each joint in the sole-bars, and more of them if required, the top of the wall being notched to receive these chairs free of downward contact with the wall; D, eyebolt-s reaching, one on each side of thewall, from the chair downwardly; E, a bar extending through the wall and projecting sidewise therefrom and engaged by the eyes of the bolts D, whereby the eyebolts serve as means for drawing the sole-bars firmly down upon the wall; F, the drying-cylinders, (shown in dotted lines and as being seven in number;) G, superdriers disposed in the usual relative position over the other driers; H, housings, one for each journal of the driers F; J, similar housings for thesuperdriers G, the housings J resting upon and being secured to and supported by the appropriate ones of the housings H; K, journal-boxes for the driers, these boxes being integrally formed with the housings and having 'a form more fully described hereinafter; L,

the feet of the housings, these feet spreading symmetrically from the vertical center of the housing and fitted toa seat upon the solebar, or, in the case of housings J, upon the tops of the housings below them, and to be secured thereto by bolts; M, top arms to the housings, the same spreading symmetrically sidewise from the vertical center of the housings substantially the same distance as represented by the spread of the feet of the housings, the tops of the extremities of these arms being adapted to have attached to them, by bolting, the feet of the superposed housings or the feet of other attaching parts, as hereinafter described; N, reach-pieces, reaching from one housing to the next and secured to the housings by bolts, these reach-pieces serving at once for the support of certain felt rolls and for the longitudinal union and stiffening of the framing in places where the framing becomes subjected to the most strains by the reason of the presence of superdriers, the reach-pieces engaging the housings J being of precisely the same form and dimensions as the reach-pieces engaging the lower housings, the upper ones being, however, turned upside down, none of these reach-pieces being needed in case superposed driers are not present; 0, crownframes, reaching from one housing to the next and having their feet bolted to the arms of the housings, these crown-frames serving as unions and stiffeners for the general framing, and also for the support of the usual felt rolls, and paper rolls disposed over the driers, these crown frames being formed with a central body narrow enough ,to go between the journals of the felt rolls which they carry, and having feet ex tending to the top arms of the housings and having outreaching arms extending to the boxes of the paper rolls which they carry, it being understood that these crown-frames are to be employed at each space between housings H in case superdriers are not present; P, the stretcher-frame for the felt of the superdriers, this frame having feet secured to the top arms of the housings below it in the same manner as the crown-frames engage the housings below them; Q, brackets secured to the top arms of the housings at the extremities of the-series of housings, these brackets serving for the support of the initial and terminal felt rolls; R, arms pivoted to these brackets by a spring-joint and serving to support the journal-boxes for the spring roll; S, the usual felt rolls; T, the usual paper rolls; U, the springroll, of which there may, if desired, be one at each end of the drier system without changing construction; V, journal-boxesofuniform charactor for the support of the rolls, these boxes being provided in connection with the reachpieces N, the crown pieces, the stretcherframe, the brackets Q, arms B, and elsewhere where the presence of a needed felt or paper roll may call for them, these journal-boxes being gapped so as to permit the free entry sidewise vof the roll-journal into them, and having a bore sufficiently larger than the rolljournals to admit of a bushing; W, the pivotbolts by which the arms R are united to their brackets, these bolts forming the pivots of hinges formed by the facial juncture oftwo disks; X, circumferential grooves in each of the journal-boxes V, leading from each side of the gap in the journal box a short distance from the gap around in the bores; Y, bushings adapted to fit within the bore of thejournal-boxes and to fit the journal of the paper rolls and felt rolls; Z, a central projection from each bushing, adapted when the bushing is in place to seat in the groove X; a, a spring-cavity formed in the contiguous hingefaces of thejoint uniting the arms R to their brackets, and b a spiral spring encircling the bolt V and disposed within the cavity a, one end of this spring being secured to each of the hinge-disks of the joint.

The sole-bars extend beyond the drier portion as far as deemed necessary to receive the press part, the making part, the cutters, calenders, 850., thus permitting the contiguous general structures forming the paper-making machine to be adjusted along said bars into desired relationship with each other.

The housings H may be adjusted along said sole-bars into desired relationship with each other, and the number of the housings H may be added to or subtracted from, as desired, without change in the formation of the parts, and superdrier-housings J may be added as desired or the superdriers may be abandoned and additional base-driers employed in the series to give the additional drying-sun face. The housings J and H, being identical with each other in form and dimension, permit of the ready transposition of parts in a mill already in operation, so that base-driers entirely may be depended upon, the number of driers lessened or increased, as desired, or spread apart or closed up more, as desired, or superdriers added as required, or extra superdriers added above the superdriers shown. The form of the housings is such as to clearly expose the felt and paper where they pass, in the usual manner, upward between the driers and the felt and paper rolls, and the form of the crown-frames O is such as to expose the edges of the felt and paper where the felt and paper turn from roll to roll, thus permitting the ready passing forward of the paperweb in case of breaks.

Thejournalboxes V, wherever found about the machine, are to be of uniform size as to bore and dimension and disposition of grooves X, the gaps in these journal-boxes being, of course, in such radial direction as will be most consistent with the ready removal of the re spective rolls. The journals of the felt and paper rolls are to be uniform in size. The bushings Y are to be throughout the machine uniform in size, so as to be interchangeable in any of the journal-boxes. They are prefer ably made of anti-friction metal of comparatively low fusibility, so as to be susceptible of casting in a metal mold in the manner in which bullets are made. A roll having been placed in its journal-boxes, a bushing, Y, is pushed over thejournal and into thejournal-box,while the projection Z passes longitudinally into the gap in thejournal-box. When the projection Z comes opposite the groove X,the bushing is turned until the projection seats in the groove, thus securing the bushing properly in the journal-boxes. To remove the roll, the bushing is turned until the projection will pass through the gap, whereupon the bushing is pulled endwise out ofthejournal-box,thus permitting the rolljournal to pass through the gap. Extra bushings of this kind kept on hand permit the ready and economical maintenance of the roll-bearings without necessity for the removal of any parts but the worn bushings. The bushings serve in preventing the displacement of the roll-journals through the gap on the journal-boxes, regardless of whether the gaps be above or below thejournals, thus rendering possible the employment of a uniform character of journal boxes throughout the machine.

The journal-boxes K for the drying-cylinders are similar in character to the journalboxes V, but of course are properly larger, and they are supplied with interchangeable bushes secured in the same manner. The

IIO

journal-boxes K are integrally formed in the central body of the housings, and above these boxes the housings have openings sufficiently large to permit the ready lifting of the drierjournal from the box and its removal from the housing.

If the pivot-bolts \V, uniting the arms R to their brackets Q, be tightened, the structure will become rigid in any adjusted position. By loosening the bolt W, the arm R will be capable of free oscillation at the hinge-joint, and the spring b will resist that oscillation in a given direction with a certain elastic force, whereby the parts serve for the proper sup port of the usual spring-roll. The tension of the spring may be readily increased by giving an additional wind or turn around its bolt.
